On the basis of analyzing performances and existing status of diesel cold-start, the paper introduces the advantages in researching diesel cold-start by applying computer simulation software. It points out that the electrically-controlled common-rail fuel injection technology and fully variable valve technology are the key points in diesel optimum design and improving its cold-start performances, from which the conclusion that the auxiliary raising temperature device is better than that in emergency start was drawn out.
